orinoco_usb: use USB API functions rather than constants

orinoco_usb: use USB API functions rather than constants

This patch introduces the use of the functions
usb_endpoint_is_bulk_in(epd) and usb_endpoint_is_bulk_out(epd).

The semantic patch that makes these changes is as follows:

@@ struct usb_endpoint_descriptor *epd; @@

- ((epd->bmAttributes & \(USB_ENDPOINT_XFERTYPE_MASK\|3\)) ==
- \(USB_ENDPOINT_XFER_BULK\|2\))
+ usb_endpoint_xfer_bulk(epd)

@@ struct usb_endpoint_descriptor *epd; @@

- ((epd->bEndpointAddress & \(USB_ENDPOINT_DIR_MASK\|0x80\)) ==
-  \(USB_DIR_IN\|0x80\))
+ usb_endpoint_dir_in(epd)

@@ struct usb_endpoint_descriptor *epd; @@

- ((epd->bEndpointAddress & \(USB_ENDPOINT_DIR_MASK\|0x80\)) ==
-  \(USB_DIR_OUT\|0\))
+ usb_endpoint_dir_out(epd)

@@ struct usb_endpoint_descriptor *epd; @@

- (usb_endpoint_xfer_bulk(epd) && usb_endpoint_dir_in(epd))
